I have spent all week working out how to do it and yes I’ve watched YouTube clips. All that is required is a new barrel a new probe and a new washer/probe guide I hope. If it goes tits up I will have the normal hissy fit blame every one and of course the not fit for purpose parts. Yes I have a gun smith on stand buy just in case.

Don't forget your chrono. .177-.22 is always interesting on the power afterwards
